ROBERT M. JOHNSON, or LANCASTER, PENNSYLVANIA.

WICK-TRIMMER.

SPECIFICATION forming part of Letters Patent No. 676,236, dated June 11, 1901.

Application filed September 1, 1900. Serial No. 28,765. (No morlelfl T0 aZZ whom it may concern.-

Be it known that 1, ROBERT M. JOHNSON, a citizen of the United States, and a resident of Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Wick-Trimmers, of which the following is a full, clear, and exact description.

The purpose of theinvent-ion is to provide a simple device which will serve to clamp a wick to be trimmed and by means of which the wick will not only be compressed at its exposed or igniting surface, but whereby also a straight horizontal line may be established at the charred portion of the wick and a substantial surface obtained at each side of the wick, upon which surfaces the shears or scissors employed for cutting the wick may bear or over which surfaces the wiping material for the wick may be drawn.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan View of the improved device, showing said device applied to a wick. Fig. 2 is an edge view of the device, a wick and burner being shown in connection therewith in dotted lines; and Fig. 3 is a trans verse section taken practically on the line 3 3 of Fig. 1.

Two blades or jaws 10 are employed, which blades or jaws when closed are in parallelism, and said blades or jaws at their rear portions cross one another and are pivotally connected by a suitable pin 11 in similar manner to the blades of a pair of shears. At the rear of the pivot 11 each blade or jaw 10 is provided with a shank 13, and each shank is usually connected with a loop 14., through which, respectively, the thumb and a finger of the hand may be passed for the purpose of manipulating the jaws or blades.

The opposing faces 12 of the jaws or blades 10 are flat, being at right angles to the plane of the jaws or blades, so that when the jaws or blades are brought together the opposing flat faces 10 will engage each other throughout the thickness of the blades or jaws and the said jaws or blades will present flat upper and lower surfaces. If desired, at a point in the flat clampin -surface of one or both of the jaws 12 a longitudinal groove 16 may be produced, as shown in Fig. 3, so that when a wick 17 is clamped or compressed between the jaws or blades 10 portions of the wick will enter the groove or grooves 16, and thus prevent the device from slipping; but preferably in the use of the device when a wick is to be clamped the jaws or blades 10 are made to rest upon the upper surface of the wick-tube, so that said jaws or blades will lie in a horizontal plane; but, if desired, as shown in Fig. 2, the cap of the burner need not be removed and the jaws or blades may rest upon the crown of the burnercap, the wick having been turned up sufiioiently, so that it may be grasped between the said blades or jaws.

The opposing faces of the portions of the jaws or blades 10 at which the pivot 11 is lo cated are recessed to produce depressions 15, so that one section of the device at the pivot may fit close to the opposing section and the side faces ofthe device be rendered substan tially in the same plane. Thus it will be ob served that when a wick 17 is held between the blades or jaws 10 of the device the wick is compressed and rendered solid at its burning-surface or point of ignition, at which point the device is to engage with the wick, and in engaging the device with the wick the upper surface of the device is designedly brought just below the whole of the charred line of thewick, so that the charred portion of the wick above the jaws or blades may be wiped off and the surface of the wick to be ignited le ft perfectly straight and practically without any spurs, so that the flame will not only be broad, but will be compact, the upper surface of the device serving as a bearing or guide for the wiping material; but should scissors or shears be employed to remove the charred surface of the wick or trim the same the upper surface of the device serves as a guide and bearing for the scissors or shears, insuring a straight and horizontal out.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A device for trimming wicks, comprising BI N 0 T L W 0 N K D M GLUE APPLYING MACHINE.

GLUE-APPLYING MACHINE.

SPECIFICATION forming part of Letters Patent No. 676,237, dated June 1 1, 1901.

Application filed October 13, 1899. Serial No. 733,470. (No model.)

To all whom, it may concern:

Be it known that 1, MARK D. KNoWLToN, a citizen of the United States, and a resident of Rochester, Monroe county, State of New York, have invented certain new and useful Improvements in Glue-Applying Machines, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof.

This invention relates to that class of machines adapted for applying an adhesive substance, such as paste or glue, to sheets of pa per or other material; and it consists of additional improvements upon the machine disclosed in Letters Patent No. 447,012, issued jointly to another and myself February 24, 1891. In this class of machines, in which the tank or receptacle for containing the glue or other adhesive substance discharges its contents by gravity directly upon the surface of arevolving pasting or gluing roller,the action of the roller causes a revolving motion of the glue at the point of its discharge from the tank, which motion of the glue produces a foaming of the same at such point, which prevents even and uniform coating of the roller by the same. Furthermore, the movementor agitation of the glue being confined to one point permits the formationof a coating or skin on the top of the glue, pieces of which, if not carefully removed from time to time, get lodged between the roller and the adjacent edge of the tank-bottom or so -called scraper and clog the flow of the glue .at such points, thus causing the roller to become coated in streaks. To avoid such objectionable features and in accordance with my present invention, I have supported a wall or partition Within the tank adjacent to its point of discharge, which partition serves to direct the flow of the glue under the action of the roller, causing the same to flow backward under said partitiontoward the rear of the tank and then return over the top of the partition to the roll. A perfect circulation of the contents of the tank is thus secured, which tends to prevent foaming, allows anyfoam-bubbles to burst before returning to the roller that might have formed, and also prevents the formation of any coating or skin on the top of the glue.

The above features and others forming part of my present invention will be hereinafter set forth in detail and pointed out in the claims.

Referring to the drawings, Figure 1 is a longitudinal Vertical sectionthrough a machine embodying my invention. Fig. 2 is a plan view of the machine with certain of the parts broken away. Fig. 3 is an enlarged side elevation of a portion of the machine. Fig. 4 is a side elevation of a portion of the machine, showing a heating apparatus connecting with the glue-tank for keeping the glue or other adhesive substance in a fluid or semifluid condition. Fig. 5 is a plan view of a portion of the construction shown in Fig. 4:, and Figs. 6 and 7 are enlarged detail views of a portion of the heating apparatus to be hereinafter referred to.

To explain in detail, the revolving pasting or gluing roller 1, to the surface of which. the glue or other adhesive substance is applied and from which said glue or adhesive substance is transferred to the paper sheets brought into contact with said roller, the opposing feed-rolls '2 2 for carrying the paper or other sheets (indicated at a in dotted lines) from the table 3 toward or into contact with the roller 1, the guide 4, located between the feed-rolls 2.2 and the roller 1 for directing the sheets passing from said feed-rolls toward and against the surface of the roller 1 approximatelyat right angles with said surface at the point of contact, the'fingers 5, resting in contact with the rollerl and acting to deflect or throw outwardly from the surface of the roller the sheets adhering thereto, and the carrier belt or apron 6, arranged in position to receive the paper sheets as the latter are removed from the roller 1 by the action of the fingers 5, all being supported and sustained upon a suitable frame 7, are of substantially the same construction, arrangement, and mode of operation as in the said Patent No. 447,012.

The tank or receptacle 8 for containing the glue or other adhesive substance, as herein shown, is supported between two verticallyarranged plates 9 9, which latter are located at opposite sides of the frame 7 and each pro-' vided with a flange 10, which rests upon the supporting-frame and is secured thereon by bolts or screws 11 11. One end of these plates IOO east 9 o is eon-enlisted to conform to the surfac of the roller 1, and the plates are supported with such end in close contact with said roller, as shown in Fig. 3. The glue-tank 8 is supported, between the plates 9 9 by means of pins or studs 12 12 at each end thereof, which project through elongated slots 13 in the opposite plates 9 and are secured at their outer threaded ends by means of nuts 14. The sides of this tank at the rear or open end of the same are also constructed to conform to the surface of the roller 1 and rest against the latter as a partial support to the tank, the. latter being held in proper horizontal position 15 against undue tilting on pins 12 12 by means of two plates 15 15, which are secured on the uper edge of the supporting plates 9 9 by the its of 'setews 16, with one side projecting eyer the upper edge of the tank, as shown in W its a means for adjusting the tank so that the edge of its bottom may be a greater or less distance from the pasting-roller 1, as may be necessary for feeding a desired quantity of glue tothe said roller, I ,have supported easements-sha t 17 in suitable bearings in t e plates 9 at the rear end of the glue-tank,

'jhsha'ft is operatively connected with the proge'cting ends of the pins 12 12 on the tank. 0 By turning this shaft 17 in the proper direction by means of a hand-wheel 19 thereon th e' operator may thereby readily adjust the genera e enable the opposite ends of the same to be adjusted to diiferent degrees of ne'a'iness to the said roller, "whereby the thick 5o ness of the coating onthelattermay be varied- 7d its opposite ends for different kinds]v small space between the same and t he ott'o'mOf, the tank and with a-s-pace between outer sides of the latter.

position of thegtank back and forth relative 1 erollerq .The connections between the aft l7 and the tank, as herein shown, conep p site screws 20 and 22, which latter are ovide d with right and left hand screwads, respectively. By this construction ng of the sleeves 2 L in theproper direc- I will cause either a forward or backward in 'einent of the tank relative to the pasting-Q rear edge and the adjacent roller and be "n its seren or .fo 'w d e. n th r ens wall of the tank, thuspe'r'mitting the passage or flow of the glue entirely around the same. By such arrangement of the par tition 2e the'glue under the action of the revolv'ifig' pasting-roller 1 'is forced back constantly beneath saidpartition and caused to flow in the direction indicated by the arrows and return to the roller over the top of the partition. Such circulation of the glue, as before-mentioned, prevents the formation of any coating or skin on the top of the same, tends toprevent foaming, and insures the glue becoming thoroughly settled by the time it returns to the pasting-roller 1.

The partition 26 in the present instance shown is supported in a removable position in the tank by means of a suitable frame composed of two plates 27 27, with which the partition is connected at its opposite ends, and

a rod 28, extendingthrough said frame-plates 2 7 27, with its ends projecting .tey'onu the sneh'n-am is removably supported in position within the glue-tank with the ends of the rod 28 resting upon the retainer-plates 15 15 and tlie for ward upper ends of the plates 27 '27 resting directly upon the roller 1, as more clearly sho'wnin Fig. 1. The frame is held in its proper position relative to the roller by means of two bracket-fingers 29 29, secure d on the plates 15 15, beneath which the ends of the rod 28 are inserted when the frame placed into the glue-tank. p

I The means for scraping the surplus glue or other adhesive substance from the roller, together with any particles of paper which may adhere thereto, and subsequently stratum g the same be fore'the glue is returned to the tank, is similar to that described the said prior patent, No. {147,012. In this instance I provide aiplate 30,whicl1 is supported at one side by the'cross-rod 28,an(l at its opposite side is formed w'i'tha sharp or thin edge adapted torest directly against; the surface of the l'Olll 1, the plate being inclineddownwardly or away from theroller and toward "the tank, as clearly shownin Fig. 1. The central porftion of this plate 30'is cut away so as to form an openingthereimdyhich opening is covered with wire'clo'th or other suitable perforated material 31, which receives the material scraped from the roller andfst'rai-nst'he glue before the latter re'tu'r'nsto the tank, 'the'passage of the glue over the scraper and through J v, H p I v the strainer being indicated by arrows in H "The lower or bottom wall 25 of the tankis;

e'f'erably incline'd downwardly toward. the;

er, as shown, and above such 'bottoin is suitably supported the wall or partition 26 for causing a circulation of the glue or other dhes'ive substance throughout the tank. '1 spartition 26, as shown, consists of aplate cfh extends across the tank with arel'a sirable to use hot water "as a mea'us for heating the g'lne, and the apparatus empioyed'for suchjpurpose according to my invention is as follows: The glueftank is provided "with a chamber 32, extending across its under side and terminating adjacent to the opposite ends of the tank, at the rear side thereof. Pipes or other suitable conduits 33 and 34 connect the opposite ends of said chamber 32 with a water-tank 35, so as to provide a circulation between the same, the said water-tank being supported upon a suitable platform 36, which through a heating-chamber 37, in which the I water passing through the pipe is heated to the proper temperature before entering the glue-tank chamber 32, the said pipe 33 being formed with a coil 39 in the heating-chamber 37, so as to provide an increased heating-surface. V

The heating-chamber 37 is formed in a frame or casting 40, which, as shown, is located beneath the feeding-table of the machine and secured to the frame 7 by means of bolts or screws 41 41. This heating-chamber 37 is adapted to be heated either by the introduction of steam therein or by gas, as may be desired. When used for steam, the chamber is made air-tight and the steam is introduced therein through a pipe 42, which opens into the chamber through a removable plate 43, having a screw-threaded connection with the lower end of the casing 40, which latter is also provided with a petcock 44, removably connected therewith for the exhauststeam. To adapt the chamber 37 for gas-heating, the plate 43 is first removed from the casting 40, the petcock 44 then detached from said plate 43 to permit of the insertion of a gas-burner attachment 45 in the openingfrom which said petoock is removed, the plate 43, with the supported gas-burner attachment, then again screwed into connection with the casting 40, and a removable plate or ring 46 at the top of the chamber then removed to permit of the entry of air therein, as shown in Fig. 7.
